A few years ago I bought a set of rear springs from XK's as I thought my original ones must be tired. The new springs sat so high that even screwing the perches down as far as possible ( I have fully adjustable rear shocks) I couldn't get it to sit right, even after a number of miles on the car. Went back to original springs. There seems to be something wrong with replacement springs. It would be nice to find a spring rate gauge and do some measurements.
